php - How to ceiling or floor a variable? -


i have tried use algorithms made other languages ceiling variables , flooring them, looked in php manual answers couldn't manage find answers finding floor / ceiling.

i have tried setting precision 0 in php.ini , didn't change anything.

i have tried 3 / 2 , want give me 1 (floor) answer or 2 (ceil)

to ceiling or floor variable simple using php builtin math functions:

$ceiling = ceil(1.5);   // ceiling of 3/2 2  $floor   = floor(1.5);  // floor of 3/2 1

ceil takes float , returns float rounded nearest integer. floor takes float , returns float rounded down nearest integer. see:

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
